Oak trees safe to prune

Divide/Move

Iris, daylily, fern, liriope, spring-blooming perennials, violets, cannas

Prep

Add compost to vegetable gardens along with organic fertilizer in prep for winter vegetables
Decide wildflower seeds and bulbs to plant in November

Lawn

Brown patch: Apply a quarter inch of compost. Apply corn meal. Find out what’s causing the problem like low drainage spots or compacted areas.
Apply corn gluten as a weed pre-emergent. Results are erratic but it does add some nitrogen to the soil
Mow high to fend off weed seeds that germinate in September’s rains. Taller grass shades them out.

Other tasks

If fall webworms are a problem, puncture webs with broom handle for wasps to naturally control. Or spray with Bacillus thuringiensis (Bt).
